The veteran star, best known for his portrayal of scheming oil baron J.R. Ewing in the original version of the soap opera, which ran from 1978 to 1991, passed away at a hospital in Texas after suffering complications from his battle with cancer.
His long serving Dallas co-stars Linda Gray, Patrick Duffy, Victoria Principal and Ken Kercheval paid tribute to the actor after news of his death emerged - and now several of his co-stars on the revamped show have also spoken out about the tragedy.
Brenda Strong tells E! News, "Being able to work with one of my childhood idols was a dream come true. He was one of the most resilient and positive people I've ever known. Larry's tremendous talent and contribution as an artist is only surpassed by his gigantic heart and how beloved he was by his friends, especially Patrick and Linda.
"He is a one of a kind and will be deeply missed. My heart breaks for his family's loss. Quite honestly, I can't believe he is gone. He lived life to the fullest and was the embodiment of the term 'light hearted.' He was and will continue to be an icon in our hearts and minds."
In a series of posts on his Twitter.com page, Jesse Metcalfe writes, "It was truly an honor to share the screen with Mr. Larry Hagman. With piercing wit and undeniable charm he brought to life one of the most legendary television characters of all time. But to know the man, however briefly, was to know a passion and dedication for life and acting that was profoundly inspirational. My deepest condolences go out to Larry's friends and family. He will most certainly be missed."
Leonor Varela added, "I am grateful to have shared a few moments in life and on screen with Larry Hagman, you inspire me to love life and appreciate every moment", while Jordana Brewster lamented, "I feel lucky and humbled to have worked with such a great man and actor. We will miss you, Larry."
Felicity Huffman, who shared the small screen with Hagman in a 2011 episode of Desperate Housewives, has also been stunned by the loss, writing on her Twitter page, "Just came down to civilization and heard about Larry Hagman, rest in peace. What a wonderful actor, honored to have worked with him", while John Cusack adds, "RIP Larry Hagman. Great actor and a really good man - had the pleasure (of) knowing him just a bit - always left smiling."
Joan Collins reminisced about working with Hagman on 1970 movie Up in the Cellar and admits he inspired her iconic Dynasty character Alexis Colby. She states, "Oh no just heard about Larry, he was magnificent as JR &amp; inspired me to play Alexis. RIP. Yes I played Larry's wife in 'Up in the cellar'. He was a lot of fun..."
Meanwhile, Hagman's daughter Heidi Kristina took to her Facebook.com page to detail her father's last moments: "Our whole family was with him. It was a loving and beautiful way to leave us."

The actress will compete against stars including former child actor Corey Feldman and Sugababes singer Heidi Range in the ice skating series when it launches this weekend (08Jan12).
Tilton, who is reprising her role as Lucy Ewing in the upcoming new Dallas season, opted to take up the challenge because she wants to grasp every opportunity since losing her partner, cinematographer Cheddy D. Hart, to a lung condition in 2009.
She tells Britain's The Sun, "I decided to do it because my fiance passed away at Christmas two years ago. It was unexpected and was right in front of me. It really made me realise we are not guaranteed our next breath, our next heartbeat - only God knows.
"I thought, 'I'm going to take every opportunity life brings.' I want to live life to the full."

Pastor Becky Fischer holds a summer camp for kids at Devil's Lake in North Dakota. She's training Christian soldiers for God's Army and Jesus Camp follows three white home-schooled Missouri children--Levi (now 13) Rachael (now 10) and Tory (now 11)--through the camp from a year ago to where they are now in their indoctrination. Filmmakers Heidi Ewing and Rachel Grady present the religious brainwashing techniques in a slow deliberate manner as the evangelical Christian adults seem to transform the kids into Stepford-like children who spew the word of God for less than altruistic reasons. The children are shown being trained to bring Christ back to America and use their "Prophetic Gifts " of which they are told they all possess. There are also scenes of children blessing a cardboard figure of President Bush saying prayers for conservative Supreme Court justice nominees and 7-year-olds in painted faces dancing spiritual war dances believing prayer can fix their malfunctioning film projector. The filmmakers try in vain to remain objective but it's impossible. As a documentary the participants of Jesus Camp come across as realistic as they can even though they are aware of the camera at all times. Some of the scenes seem to play to the cameras in disturbing reality as the angelic faces are moved to tears by their religious fervor or turned into unworldly contortions as they speak in tongues. Levi wants to be a mega-church pastor speaking to congregations of thousands while Rachael wants to be a missionary in far-off places and is bent on recruiting her neighbor. Tory spreads her message through dance and attends anti-abortion rallies. Pastor Becky is also shown in revealing moments especially as she obsesses more about her appearance than Tammy Faye Baker would. Pastor Becky obviously allowed incredible access to the filmmakers for Jesus Camp and maybe she’ll be pleased with the way the film will get her word out. But Jesus Camp seems more suited for TV than the big screen. The ideas presented are not even remotely balanced. Well-made feature film documentaries don’t have to be unbiased but they should at least strive to address some opposite points of view. Air America radio host Mike Papantonio who is a Methodist gives the only contrary commentary about these camps but he's rather namby-pamby about it all. Those who may expect more answers from Jesus Camp--on what would make people like Pastor Betty take these kids and coach them into becoming religiously intolerant and rigid thinkers--could be sorely disappointed.

The organizers of Michael Moore's Michigan film festival have ignored pleas from the distributors of Jesus Camp to withdraw the upcoming movie from the event, over fears the film would be tainted by Moore's anti-conservative views.
The Oscar-winning filmmaker is well-known for his negative views on President George W. Bush and his government thanks to mega-hit documentaries Bowling for Columbine and Fahrenheit 9/11.
Moore is screening Heidi Ewing and Rachel Grady's documentary Jesus Camp--about a summer camp for born-again Christian children--at his annual Traverse City Michigan Film Festival today and tomorrow.
However, distributors Magnolia Films, who acquired the North American rights to the movie last week, believe Moore's association with the movie would hurt audience figures among conservative audiences.
Magnolia Films president Eamonn Bowles says, "The reality of the world we live in today is that if Michael Moore endorses it, tens of millions will automatically reject it."
Jesus Camp producers gave the festival's organizers permission to screen the film weeks before their deal with Magnolia and a festival spokesman has confirmed the screenings will still take place.
